Kensington Palace said in a statement on 30 August: “The Duke and Duchess of Cambridge, accompanying Prince George, will be met on arrival at the school by the Head of Lower School, Helen Haslem, who will then escort Their Royal Highnesses to Prince George’s reception classroom.”

He wrote: “This is clearly a significant moment for their family and most certainly for Thomas’s.

“Like so many parents, the Duke and Duchess have put a great deal of thought into the choice of their eldest child’s first ‘big school’.”

In a statement on the school website, Thomas wrote: “Whilst we are proud of our record of senior school entrance and scholarship successes, we place a greater emphasis on a set of core values, which include kindness, courtesy, confidence, humility and learning to be givers, not takers.

“We hope that our pupils will leave this school with a strong sense of social responsibility, set on a path to become net contributors to society and to flourish as conscientious and caring citizens of the world.”
